General Description
The HT75XX series is a set of three-terminal
high current low voltage regulator implemented in CMOS technology. They can deliver
100mA output current and allow an input voltage as high as 24V. They are available with several fixed output voltages ranging from 3.0V to
8V. CMOS technology ensures low voltage drop
and low quiescent current.
Although designed primarily as fixed voltage
regulators, these devices can be used with external components to obtain variable voltages
and currents.
